Installation
3.  Adjust image size and position of Set B with ZOOM ring, VERTICAL adjuster, 
HORIZONTAL adjuster and FOCUS ring to fully overlap the image of Set A.  
NOTE  • Fine adjustment of image size and position later by electrical 
function, such as KEYSTONE and PERFECT FIT, cannot widen the 
image size, so it is important to fully overlap the image of Set A by optical 
adjustment.  
• If you try to operate Set B with the remote control, Set A may react as well.  
It is recommended to operate Set B with the control panel on Set B.
• If you install two projectors side by side, also adjust image size and position 
of Set B to fully overlap the image of Set A.  
• If you use Simple Stack, it is recommended to disable the remote control 
on Set B by KEY LOCK and operate it by the control panel, or to operate 
it by a wired remote control, since Set A will react to the remote control.

1.  Turn on Set B.
NOTE  • After turning on Set B, make sure that the image of Set B is not 
remarkably inclined compared with the image of Set A.  If it is inclined too 
much, rotate the elevator feet of Set B to adjust the angle roughly.  Check 
again that there is about 1 mm space between a protrusion at the bottom of 
Set B and the top case of Set A.
